Abstract
The invention discloses a rubber shock absorber. The rubber shock absorber comprises a mounting base, a positioning shaft, a round cap and a rubber supporting body. The top of the positioning shaft is fixedly connected with the round cap, and the rubber supporting body is made of vulcanized rubber and is arranged between the positioning shaft and the round cap. The mounting base is embedded in the rubber supporting body and is not in contact with the positioning shaft. The shock absorber plays a role in reducing vehicle vibration transmitted to the interior of a vehicle from a vehicle body, and reduces the noise. The structural and stress state is reasonable, the product durability is improved, and the service life is prolonged. A safety protection device is arranged, it is ensured that in the running process of the vehicle, derailment cannot happen, so that the safety of the train is achieved.
Description
Technical field
The invention belongs to shock absorber, be specifically related to the rail traffic vehicles partition shock absorbers such as a kind of high speed train, subway.
Background technology
The partition damper structure that current vehicle is installed is unreasonable, and rigidity is comparatively large, and damping is less.In vehicle operation, effectively suppression car body passes to the vibration in car, causes noise in car comparatively large, reduces the traveling comfort that passenger takes, simultaneously to the inner components of car body, also result in certain infringement.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the object of the invention is to, provide a kind of partition shock absorber, solving traditional vehicle partition damper structure unreasonable, car internal vibration is large, the problem of traveling comfort difference.
Partition shock absorber provided by the invention, comprise mount pad, fix shaft, circle cap, rubber mount body, the top of described fix shaft is fixedly connected with circle cap, described rubber mount body is polysulphide rubbers, be arranged between fix shaft and circle cap, described mount pad is embedded in rubber mount body, does not contact with fix shaft.
The material of the mount pad of partition shock absorber, round cap, fix shaft is aluminum alloy, carbon steel, corrosion-resistant steel.
Fix shaft center can be unthreaded hole or tapped bore.
Be provided with gap in the middle of rubber mount body and circle cap, give the deformation space that rubber mount body is enough, the effect of heat radiation can be had simultaneously.
Mount pad is embedded in rubber mount body, does not contact with fix shaft, can realize fix shaft and be connected with the elasticity of mount pad.
Circle cap and mount pad all adopt angle and arc transition, and stress when can reduce shock absorber work is concentrated, and extends shock absorber service life.
Partition shock absorber provided by the invention, its beneficial effect is, this shock absorber plays and reduces vehicle is delivered to car internal vibration effect by car body, reduces noise; Structure and strained condition rationally, improve durability of product, and service life increases; Be provided with safety guard, ensure can not come off in vehicle operation, in order to avoid cause train safe problem.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of the embodiment of the present invention.
Mark in figure:
1. mount pad; 2. fix shaft; 3. justify cap; 4. rubber mount body.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, to rubber damper provided by the invention, be described in detail.
Embodiment
With reference to Fig. 1, the rubber damper of the present embodiment, it comprises mount pad 1, fix shaft 2, circle cap 3, rubber mount body 4, described fix shaft 2 is established and is fixedly placed on mount pad 1, the top of fix shaft 2 is fixedly connected with circle cap 3, described rubber mount body 4 is polysulphide rubbers, is embedded between fix shaft 2 and circle cap 3.
Rubber mount body 4 hardness: shore hardness 40 degree of-80 degree; The maximum outside diameter of circle cap 3: 20mm-300mm; Height 10mm-100mm; Rubber damper technical parameter: 1) axial static rigidity value: 100-5000N/mm; 2) radial Static stiffness value: 100-5000N/mm; 3) the rigidity output ratio of Q-switching to free running: 1.1-5; 4) coefficient of losses value: 0.01-0.3.
